The Shimano GRX RD-RX810 Rear Derailleur brings precision, silence, and stability to gravel and adventure riding. Designed for 11-speed drivetrains, it features SHIMANO SHADOW RD+ technology with an integrated chain stabilizer mechanism that minimizes chain slap and drops on rough terrain.
With a toggle ON/OFF clutch system, you can easily adapt the derailleur for mixed conditions—engaging the stabilizer for off-road stability or disengaging it for smooth road performance. Engineered with gravel-specific clutch tension and wide compatibility for road DUAL CONTROL LEVERS, the GRX RD-RX810 ensures reliable and quiet shifting across all terrains.
